From this station I can perceive the western termination of the Trachytic range, and I am now about to explore the country between it and the Nammoy, and the further course of this river; and in the event of its continuance in a favourable direction, I shall fix my depot on its right bank, whence I now write, and descend the stream in the portable boats.
I have the honour to be, Sir, Your most obedient servant, T.L.MITCHELL, SURVEYOR-GENERAL The Hon.

The Colonial Secretary.
* * * * * Peel's River, 29th February, 1832.
SIR, I have the honour to inform you, for the information of His Excellency the Governor, that I have reached the left bank of this River with my whole party on my return from the northern interior, having explored the course of the river referred to in my letter of 22nd December last, and others within the 29th parallel of latitude.
There was so much fallen timber in the Nammoy, and its waters were so low, that the portable boats could not be used on that river with advantage, and I proceeded by land in a north-west direction, until convinced by its course turning more to the westward that this river joined the river Darling.

I therefore quitted its banks with the intention of exploring the country further northward, by moving round the western extremities of the mountains mentioned in my former letter, and which I have since distinguished in my map by the name of the Lindesay Range.

These mountains terminate abruptly on the west, and I entered a fine open country at their base, from whence plains (or rather open ground of gentle undulation) extended westward as far as could be seen.

On turning these mountains I directed my course northward, and to the eastward of north, into the country beyond them, in search of the river KINDUR; and I reached a river flowing westward, the bed of which was deep, broad, and permanent, but in which there was not then much water.
THE RIVER KARAULA.
The marks of inundation on trees, and on the adjoining high ground, proved that its floods rose to an extraordinary height; and from the latitude, and also from the general direction of its course, I considered this to be the river which Mr.Cunningham named the Gwydir, on crossing it sixty miles higher, on his route to Moreton Bay.
